PUNGHING- AND RIVETING MACHINE.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed June 24, 1908. Serial No. 440,083.

This invention relates to punching and, riveting machines of a generaltype shown in a previous patent of mine No. 877,i19, January 21, 1908,and shown in a prior application of mine executed June 9th, 1908. Thistype of machine is designed for punching and riveting pipe, theoperation requiring several different tools, any one of which mayreadily be laced in operative position.

11 the two former inventions of mine, above referred to, the tools weremounted on a carrier and were arranged outof line with each other as thecarrier had a fixed plane of shifting movement and it is necessary thatcertain tools act in difi'erent planes.

The main object of the present invention is v to produce thenecessarycoaction between the tools without necessarily requiring the tools to bearranged on the carrier in line with each other. More specifically, toenable the tools to be arranged on the carrier in line with each'other,or substantially so and to provide means for roducing the necessarycoaction between fine tool on the carrier and its male or female tool onthe stake by providing a relative shift of position between the two setsof tools. This may be accomplished in various ways, several forms beingerein shown. v

Referring to the drawings :Figure 1 is a side elevation ofone form ofmachine. Fig. 2 is a front elevation of the form shown in Fig. 1 withthe background of the machine Fig. 6 is a side elevation of a machineequipped with a turret tool carrier and hav ing the stake dies slidablyarranged in the stake, part of the stake being shown in section. Fig. 7is a section on lineal-x Fig. 6. Fig. 8'is a side elevationshowingmerely the Fig. 5 is an end elevation of what is shown in Fig.4..

end portions of the overhanging arm and stake, the former being equip edwith a sliding tool carrier, and the latter having slidable stake dies.Fig. 9 is a side elevation of the front end of the overhanging arm andthe stake, illustrating how the sliding tool carrier can be employed inlieu of the turret head of Fig. 1 in connection with the sliding stake.Fig. 10 is a front elevation of what is shown in Fig. 9, part of thetool carrier being in section.

Referring to the form shown in Figs. 1, 2 and 3, 1 designates the frameof the machine having an overhanging arm'2 underneath which is arrangeda stake 3, the latter being longitudinally slidable in the frame 1 bymeans of a pinion 4 which meshes with a rack 5 formed on the stake 3.Pinion 4 is mounted on a shaft 6 which may be operated by a handle 7. Inorder to secure a close fit of the stake within the frame, after it hasbeen adjusted to the proper position, a ortion of the stake isconstructed with a we go 8 which may be operated by rack and inionsimilar to that previously described. ounted to slide vertically in theend of the arm 2 is a head 9 operated by a crank 10 and box 11, thecrank 10 being formed on the shaft 12 which extends through the arm 2.The head 9 has-a pin 9 on which is j ournaled a turret tool carrier 13,the latter being operated and locked in various angular positions bymeans of a looking lever 14 which is adapted to engage in notches 15formed in the head 9, as shown in Fig. 2. Secured to the tool carrier 13is a lap laying tool 16, a punch 17 and a riveting tool 18, all of whichtools are arranged in line with each other so that as the tool carrier13 is rotated all of said tools rotate in the same plane. Fixed near theouter end of stake 3 are; stake dies comprising a female die 19, whichis adapted to coact with the punch 17, and an anvil 20, which is adaptedto coact either with the riveting tool 18 or with the laplaying tool 16.When the punch is to be used, it is brought into central position, asindicated in Fig. 2, and the stake 3 is so adjusted that the die 19 liesdirectly under the punch 17. If the riveting tool 18 is to be used, thetool carrier is turned to bring the riveting tool 18 into centralposition, and the stake 3 is adjusted longitudinally to bring the anvil20 underthe riveting tool, the stake beits ing readily shifted by firstoperating handle 7 to loosen wedge 3, whereupon handle 7 may be operatedto shift the stake, which, having been brought into proper position, islocked and firmly held in frame 1 by operating handle 7 to close thewedge 8. If the lap laying tool is to be used, the tool carrier isturned to bring the lap laying tool 16 into central position.

If desired, the previous form can be slightly modified by substitutingthe sliding tool carrier shown in Figs. 9 and 10 in place of the rotatintool carrier 13 of Figs. 1, 2 and 3. The sliding tool carrier of Figs. 9and 10 comprises a sliding tool carrier 20 which is slidabletransversely in the lower end of the sliding head 21, the latter havingan enlargement 22 formed at its lower end, but otherwise having the samegeneral construction as previously described. The tool carrier 20 isprovided with three tools 16, 17 and 13, all of which are arranged inline with each other so that when the tool carrier 20 is shifted thethree tools move in a single plane. The tool carrier 20 may be operatedand locked in either of its three positions by means of a shaft 23 havina dog 24 which is adapted to engage with eit er of three notches 25formed in the head 21. The shaft 23 is operated by a handle 26, a spring27 serving to normally hold the offset dog 24 in engagement with anotch. By turning handle 26 the offset dog 24 may be disengaged from anotch to permit the tool carrier to be shifted. As shown in Figs. 9 and10 the tool carrier 20 is adjusted with the punch 17 in operativeposition, and the sliding stake 3 is in a corresponding position. Byshifting the tool carrier 20 to bring either of the tools 16 or 18 intooper ative position, the sliding stake 3 will be correspondingly shiftedas in the previously described form.

In the forms shown in Figs. 6 to 8, the relative shift between the stakedies and tools on the head is accomplished by shifting the tools in thestake. In Fig. 6 the revolving tool carrier 13 employed is the same asused in Figs. 1 to 3. 3O designates the stake which is fixed in theframe 1, and near its outer end the stake has a dovetailed groove 31 inwhich is slidably mounted a block 32 as shown in Fig. 7. A groove 33having vertical walls adjoins the dovetailed groove 31 which permits theblock 32 to be inserted or removed from its sliding seat in the stake.The block 32 is provided with a female die 34 for coaeting with thepunch 17, while the rear portion of the block 32 is formed with an anvil35 which coaets with the riveting tool 18 or lap laying tool 16. Theblock 32 is shifted by means of an operating rod 36 which is connectedto it and extends through the stake 30. The rod 36 may be actuated inany suitable manner, as, for exam )lG, by the slotted rock lever 37,link 38 and hand lever 39 which is movable over a notched sector 40.Thus by onerating hand lever 39 either the anvil 35 or tne die 34 may beshifted into operative position underneath the tool ear rier 13.

Fig. 8 shows a slight modification over Fig. 6 in that the sliding toolcarrier 20 is substituted for the revolving tool carrier 13. The slidingtool carrier 20 is similar to that shown and described in connectionwith Figs. 9 and 10.

In the form shown in Figs. 4 and 5, the tools are carried in what may betermed a compound head which comprises a lower sliding tool carrier 45which is slidably mounted in an intermediate carrier 46, the latterbeing slidably mounted in an enlargement 47 on the lower end of thesliding head 9. The intermediate carrier 46 is mounted to slide in adineetion longitudinally of the stake 48, and the lower tool carrier 45is mounted to slide at right angles to the movement of the intermediatecarrier 46. The tool carrier 45 is operated and locked in its variouspositions, with respect to the carrier 46, by latch mechanism 26 similarto that shown in Fig. 10, while the carrier 46 is operated and locked inits two positions on the head 9 by latch mechanism 26, both latchmechanisms being the same with the eXce ation that only two lockingnotches are employed with latch mechanism 26' as the carrier 46 requiresbut two positions, one of which holds the line of tools over the femaledie 19 and the other locks it in position over the anvil 20.
